The average price of gas in Connecticut and North Haven is hovering around $4 a gallon, according to price tracking website Connecticut Gas Prices.
A month ago, the average price in Connecticut was $3.80. The prices throughout the state remain far more expensive than the national average, which most recently was $3.74.
In North Haven, BJ's is at $3.85/gallon, while Mobil and Valero are over $4, according to the website.
Patrick DeHaan, senior petroleum analyst for GasBuddy.com, the parent company of Connecticut Gas Prices, said Tropical Storm Isaac could affect oil prices, but it appears that the storm is weakening.
"It's entirely within the realm of possibility that we see refinery outages, oil production losses and gasoline supply issues - essentially all the things you don't want to happen," DeHaan said in a statement. "While this storm doesn't currently appear as powerful as other storms that have caused similar concern, we're continuing to watch the situation develop."
The price per gallon last averaged $4 in Connecticut back in April.
